Objectives/Goals

The objective of my experiment was to find out what fertilizer made sweet peas grow the most. I believed that the two conditions treated with worm compost tea and regular water would grow the most.

Methods/Materials

I planted sweet peas in a soil mix and treated 6 different groups: plain water, worm compost tea, and four different fertilizers: nitrogen, phosphorus, potassium, and micro-nutrients. There were five plants in each condition. I measured the height three times and calculated the difference in centimeters.

Results

The peas treated with worm compost tea grew the most.

Conclusions/Discussion

My hypothesis was proven accurate. The measurements were close between worm coompost tea and phosphorus fertilizer, and with more time for the peas to mature, a stronger conclusion might be reached. I learned that I cannot compare height if the plants are not the same height before I start to treat with different fertilizer. 3rd party contributor
